This paper demonstrates that every major computational architecture from 1936 to 2026 — including the Turing machine, Von Neumann architecture, McCulloch-Pitts neuron, perceptron, backpropagation, transformer, and Claude Code three-layer memory — independently requires three irreducible components exhibiting collapse-on-removal. The same triadic structure appears in Peircean semiotics, Shannon information theory, thermodynamics, molecular biology, and neutrino physics. The P × I × Pr invariant (Reality = Pattern × Intent × Presence), first formalized May 2025, provides the meta-ontological explanation: coherent instantiation requires exactly three irreducible factors in multiplicative conjunction, and no system can function with fewer. 15 independent systems across 8 domains spanning 160 years confirm the invariant with zero counterexamples.
